基于ECDIS系统的舰船天文导航系统的设计方案

本文提出并建立了一种新的舰船组合导航系统，即基于ＥＣＤＩＳ（电子海图）系统的舰船天文导航系统。设计了系统的总体框架结构，建立了系统中有关的数学模型，给出了系统的软件设计方法和具体实现。最后给出了一个用本系统定位的实际例题。研究结果表明，本系统的设计方案和数学模型合理有效，为解决天文导航的定位精度和自动化两个方面的难题提供了新的思路和重要的参考。

Design Scheme for the Marine Celestial Navigation System Based on the ECDIS System

A New integrated marine navigation system, the marine celestial navigation system based on the Electronic Chart Display and Information System (ECDIS), is presented and established in this paper. An overall structure of the system is designed and a mathematical model related to the system is established. The design and realization method of the software is advanced, and the navigation and positioning example is offered in the end. The research results show that the design scheme and the mathematical model are reasonable and effective, which provide a new clew and reference to settle the problems such as accuracy and automation of the celestial navigation.
